 Functional testing of vIMS in OPNFV Release 1 will be limited to a basic, non-scalable and non-fault-tolerant deployment of IMS. Furthermore,​ in this release the vIMS will perform only control plane functions (i.e. processing of SIP signaling messages) and will not be passing RTP media streams. Functional testing of vIMS in OPNFV Release 1 will be limited to a basic, non-scalable and non-fault-tolerant deployment of IMS.

 +===== Networking Requirements =====
 +All of the software components listed above need to be able to connect to each via IP.  There are no other specific networking requirements. ​ It does not matter how the IP connectivity is provided, i.e. whether it uses VLAN, VXLAN, GRE etc.
